In 2018, Russia banned Telegram although it reversed the prohibition two years later. But the Ukraine Crisis Media Center's Tsekhanovska points out that communications are often down in zones most affected by the war, making this sort of cross-referencing a luxury many cannot afford. Groups are also not fully encrypted, end-to-end. This includes private groups. Private groups cannot be seen by other Telegram users, but Telegram itself can see the groups and all of the communications that you have in them. All of the same risks and warnings about channels can be applied to groups. I want a secure messaging app, should I use Telegram? For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content.
